On the Ubuntu host
tar xf /srv/domains/linuxfromscratch.org/LFS-7.7/gmp-6.0.0a.tar.xz
cd gmp-6.0.0/
./configure \
--prefix=/usr/local \
--enable-cxx \
--docdir=/usr/local/share/doc/gmp-6.0.0a
Notes:
1) This link gets created.
gmp-mparam.h -> mpn/x86_64/bd2/gmp-mparam.h
Cf the "bd2" with the "bd1" in the compilation's -mtune and
-march flags: two different views of the same processor ?
2) Went with a "make -k check" so you can see all the failures.
3) I noticed a few possibly related messages in the dmesg output
on the host that also appear inside the VM's dmesg - this might
be the show-stopper.
Attached:
ub1204-config.status
ub1204-config.log
make 2>&1 | tee ub1204-make.out
make html 2>&1 | tee ub1204-make_html.out
make -k check 2>&1 | tee ub1204-make-k_check.out
Attached
ub1204-make.out
ub1204-make_html.out
ub1024-make-k_check.out
ub1204-dmesg
Repeated same inside the Xen VM (CentOS 6.6)
Notes:
gmp-mparam.h -> mpn/x86_64/bd2/gmp-mparam.h
Attached:
cent66-config.status
cent66-config.log
cent66-make.out
cent66-make_html.out
cent66-make-k_check.out
cent66-dmesg
Repeated same inside the LFS chroot
Notes:
LFS chroot build uses --prefix=/usr not /usr/local
gmp-mparam.h -> mpn/x86_64/bd2/gmp-mparam.h
Attached:
lfs_77-config.status
lfs_77-config.log
lfs_77-make.out
lfs_77-make_html.out
lfs_77-make-k_check.out
lfs_77-dmesg
I believe that the "trap invalid opcode" messages seen in the dmesg
are probably the root cause, or the symptom of the root cause, of the
issue but I attach all the other stuff to avoid having to read any minds !
Also downloaded the latest GMP snapshot, gmp-6.0.0-20150409.tar.lz,
as per Marc's suggestion and built it in the Ubuntu 12.04 box.
Notes:
1) Configure's summary stanza ends with a slightly Host type to 6.0.0a
Version: GNU MP 6.0.0
Host type: piledrivernoavx-unknown-linux-gnu
ABI: 64
Install prefix: /usr/local
Compiler: gcc -std=gnu99
Static libraries: yes
Shared libraries: yes
2) The gmp-mparam.h link is, as before on the Ubuntu 12.04 box,
linking to a "bd2" file:
gmp-mparam.h -> mpn/x86_64/bd2/gmp-mparam.h
3) The compilations still use the "bd1" annotations
4) I still see "Illegal Instruction" failures in the "make check"
# grep " tests " ub1204-20150409-make-k_check.out
All 8 tests passed
3 of 45 tests failed
16 of 63 tests failed
1 of 14 tests failed

13 of 20 tests failed
although there seems to be one less test in the snapshot, compared to
the 6.0.0a greps, where all three showed:
All 9 tests passed
3 of 45 tests failed
16 of 63 tests failed
1 of 14 tests failed
3 of 27 tests failed
All 7 tests passed

=======
When I saw the same failures on the "bare metal" Ubuntu box, I didn't
bother with building on the VM or the LFS chroot.
What I will also do, once I reboot out of the Xen environment, is to try
the 6.0.0a and snapshot sources against a "pure" kernel: just for
completeness.
Still hoping this is something really obvious that I have missed,
Kevin
